Introduction
The Trusted TM Versatile Field Termination Assembly (VFTA) T8842 is primarily designed to act as the
main interface between field devices associated with the detection and suppression of fire and gas
hazards, and the Trusted
TM
TMR Zone Interface Module T8448. It is also used as the interface for the
Trusted
TM
TMR Valve Monitor Module T8449, for which digital outputs to solenoid valves alternate with
valve position analogue inputs.
Each channel of the VFTA is configurable to enable a variety of field devices to be connected. These
include devices generating both analogue and digital input signals, and output devices requiring a
digital signal at up to 28V dc.
Features
40 channels per VFTA each configurable as inputs or outputs.
Industrial standard field device connections (2 or 3 wire).
Standard DIN rail compatibility.
Simple installation and connection.
Simple configuration using plug-in fuses and built-in resistors.
18-28Vdc operation.
Field power supply arranged in five groups of eight channels.
Option to supply power from a controllable output for each group.
Fused field power supply per channel.
